Question 4 1 pts Which of the following mole ratios CANNOT be derived from the reaction 2 502 (g) + O2 (g) + 2 H20 (1) --> 2 H2SO4 (aq) ? 02 mol SO2 2 mol H2SO4 2 mol H2SO4 2 mol O2 0 1 mol O2 2 mol H20 O 2 mol O2 1 mol O2 2 mol H20 2 mol SO2

Answer 1

Q 4) According to the given reaction.

2 moles of SO_{​​​​​2} reacting with 1 mole of O_{​​​​​​2} and 2 moles of H2O to give 2 moles of h2SO4

So 2 mole h2SO4 vs 2 mole O2 ratio can't be derived.

Q 1) Coefficients in balanced reactions tells about

1) Number of molecules of reactant and product involved in a chemical reaction.

2) Relative number of moles of each substance involved in a chemical reaction.

Q 3) 1) 4 molecules of NH3 requires 5 molecules of O2 to react as mentioned in the balanced reaction.

2)with 4 moles of NH3 and 4 moles of O2 , O2 is the liniting reagent beacause 4 moles of nh3 reaquire 5 moles of o2 which we are not provided with.

3)for every 1 mole of nh3, 1 mole of NO is reacted

Because in the balanced reaction both nh3 and NO having same number of moles

4) if 8 moles of nh3 are used up then 10 moles of O2 are also uused up

Because in the balanced reaction, ration of moles of nh3 : O2 = 4:5
